Asked by May 09, 2015 at 04:00 AM about the 2002 Mercury Sable GS

Question type: Maintenance & Repair

Changed crank pos. sensor, cam sens., 5 & 6 injectors, Intake plenum o-rings and
rotated plugs. Made sure I'm getting spark and still getting 5 & 6 misfire codes. In fact
engine is running rough and there is no difference if i disconnect 5 & 6 plug wires, yet an
noticeable difference w/ #4 wire pulled. What am I missing????!

Hmm, I've seen in the past that you can easily cross #5 and #6 wiring harness connectors to the COPs when changing the plugs on a 3.0L duratec if you didn't mark them. Try swapping #5 wiring to #6.

Have more than triple checked wires, but it is possible the coil pack was wired improperly. I'll try it this evening and post the results.

Replacement coil pack had 5 & 6 outputs flipped from the factory output. thanks for the help.

In other words factory coil pack clockwise order is 465123, and the replacement order is 456123. Hadn't even considered this.

We're you the original owner? Maybe someone else might have gotten is screwed up or the local garage. Looking at the engine,123 is in the back, 456 is in the front. Glad I was able to help. Cheers!

I don't know who the original owner was, It's my nieces car. But the original " motor craft" coil read:[from the front of the car position], left to right was 321, back was 465.
